SPECIPICATION formingpart of Letters Patent N0. 337,157, dated March 2,1886.

Application filed December 28, 1885. Serial No. 186,843. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM C. HOMAN, of Middletown, in the county ofMiddlesex and State of Connecticut, have invented new ImprovementsinCall-Bells; and I do hereby declare the following,`when taken inconnection withaccompanying drawings and the letters of reference markedthereon, to be a full, clear, and exact description of the same, andwhich said drawings constitute part of this specification. andrepresent, in

Figure l, a vertical central section; Fig. 2, a vertical central sectionof the upper part of the post at right angles to Fig. l; Fig. 3, amodification.

This invention relates to an improvement in that class'of call-bells inwhich the bell is arranged upon a Vertical post and the hammer operatedby a device above extending down through said post into connection withthe hammer, and particularly to that class in which the strokes arerapidly repeated. In the usual construction of this class of bells themechanism is somewhat complicated, and in most cases requires theemployment of a spring.

The object of this invention is to construct a bell very simple inoperation, cheap, and avoid the employment of a spring; and it consistsin the construction as hereinafter described, and particularly recitedin the claim.

A represents the base of the bell,constructed with or adapted to receivea post, B, the said post constructed with a slot, a, at its upper end,and with an arm, b, on each side of said slot, and is also provided witha screw thread upon its outside above the arms b.

C is the bell,constructed with an internallyscrew-threaded centralopening adapted to set over the post and engage with the thread o n thepost.

D is a hammer hung between the arms b, so as to swing freely therein,and constructed with a tail, d, extending into the slot a.

E is a wheel hung within the slot a, so as to tail d ofthe hammer.

revolve in a vertical plane over the tail ofthe hammer. The edge of thewheel is construct ed with several notches, forming intermediateprojections, the arrangement of the wheel being such that theprojections will strike the The wheel is best secured in the slot by astud having a screwthreaded head, which will engage with one side of thepost and force the other side from it, thus spreading the divided partof the post in the opening in the bell, and so as to set the bell in itsposition on the post.

To strike the bell, it is 'only necessary to revolve the wheel E,whichis easily done by drawing the finger over it, and the projections willsuccessively strike the tail of the hammer and cause the hammer tostrike the bell, the rapidity of the strokedepending only on thevelocity of the wheel, the stroke being repeated as many times as theprojections on the wheel strike the tail. The projections on the wheel Eare rounded, so that revolving it in either direction will cause thebell to be struck.

Instead of constructing the tail of the hainmer to extend upward intothe slot a, a spindle may be arranged through the post, one end to reston the tail and the other to engage with the wheel E, as shown in Fig.3, the result being the same.

It will be understood that the hammer and bell may be secured to thepost in any of the well-known constructions of call-bells.

I claim- In a call-bell, the combination of a base, A, provided with apost, B, bell C, secured to said post, and hammer D, hung upon the postB and constructed with atail, d, with a notched wheel, E, hung in thepost B, and adapted to impart swinging movement to the hammer,substantially as described.
